Womanizer Premium is a high qaulity air pressure vibrator that provides an optimal stimulation of the clitoris. The toy creates a sucking sensation by using air pressure waves. It has 12 intensity settings with a softer first level and a harder max level compared to the Womanizer W500. The Womanizer Premium is whisper quiet (<40dB) and has an auto pilot function which gradually levels up the intensity. This way you can fully concentrate on the sensation without knowing when the intensity will change. The Womanizer is also provided with a Smart Silence function. This ensures an even quieter device, as it only turns on once it is near the body. This way there is no accidental turning on and no disturbing noises. The toy is completely waterproof and is easy to clean with water and toy cleaner.
